1. Why should you register the inventions in the area of drying, furnaces, kilns, ovens, retorts, or heat exchange?

The area of drying, furnaces, kilns, ovens, retorts, or heat exchange covers a variety of products and methods that play very important roles in our modern life. Companies that do business in this area need to always update and improve their products in order to meet the demand and be competitive in the market. However, after inventing an invention, if the owner of the invention does not have sufficient methods to protect the invention, there will be risk where the invention is copied or even stolen, thus causing huge loss to the owner. One of the most effective ways to prevent this situation is to register the invention with the authority for a patent. The owner can receive big return from the investment in the invention as below:

- The patent will be a solid legal basis that a company needs in order to prove its ownership of an invention if there is a dispute related to the invention. The company can also base on the patent to send requests to the authority to handle any infringement of other companies, organizations or individuals.

- One of the biggest advantages is the exclusive rights that the owner will have in manufacturing, trading or distributing some products/services based on the invention. This prevents other parties taking advantages or exploiting the invention without the permission of the owner. The company can reduce competition and strengthen its position in the market.

- In terms of business benefits, the owner of an invention can use the patent as an advantage in attracting business partners or investors because the business partners and investors will see the patent as evidence of an innovative and high technology company. It also helps a company a lot in branding strategy and plan.

- Last but not least, the owner of an invention will also receive economic benefits from activities of licensing or transferring the patent. After being registered, a patent can also be recognized as an asset to be contributed to the capital of other companies or to be used as collateral for bank loans.
